Trihydrochloric acid, also known as hydrochloric acid, is a colorless, highly corrosive and toxic liquid with a strong odor. It is a strong acid with the chemical formula HCl and the CAS number 1133-80-8.
Trihydrochloric acid is produced in the laboratory by the reaction of hydrogen chloride gas with water. It is a component of the gastric acid produced in the human stomach, and is widely used in the industry for a number of purposes. It may be used to clean metal surfaces, to etch metal for printing, and to dissolve calcium carbonate. It can also be used in industrial processes such as metal pickling, oil well acidizing, and ore leaching.
Trihydrochloric acid is also used in the production of inorganic salts, such as sodium chloride, potassium chloride, and calcium chloride. It is also used in the manufacture of fertilizers, dyes, and explosives. In addition, it is used in the production of household cleaners, soaps, and detergents, as well as in the production of pharmaceuticals.
Trihydrochloric acid is extremely corrosive and should be handled with extreme care. It should be stored in a cool and dry place, away from heat and moisture. It should also be kept away from combustible materials as it is highly flammable. Protective clothing, such as eyewear and gloves, should be worn when handling the acid.
